|"do i need to re install?"|
Your system isn't even attempting to load Windows so why would you think you would need to reinstall? Enter the BIOS & make sure your HDD is being properly recognized. Check the boot order to make sure it's configured correctly (CD/DVD should be listed before the HDD), & see if there's a way to check the CPU temp.
Try booting off a Linux live CD & see if that works.
